Django REST框架POST文件错误(使用ModelResource)

class MyImageResource(ModelResource):
    model = Image

在urlpatters中：

url(r'^image/$',ListOrCreateModelView.as_view(resource=MyImageResource)),url(r'^image/(?P<pk>[^/]+)/$',InstanceModelView.as_view(resource=MyImageResource)),

Image模型很简单：

class Image(models.Model):
    image = models.ImageField(upload_to=get_file_path)
    name = models.CharField(max_length=256,blank=True)
    description = models.TextField(blank=True)

在浏览器中测试REST页面,效果很好.甚至用文件发布数据.

我的问题是我想创建一个简单的python应用程序来发布数据.我使用了简单的urllib2,但是我得到500内部错误或400错误请求：

poza = open('poza.jpg','rb')


initial_data = (    
    {'name','Imagine de test REST'},{'description','Dude,this is awesome'},{'image',poza},)

d = urllib.urlencode(initial_data)
r = urllib2.Request('http://localhost:8000/api/image/',data=d,headers={'Content-Type':'multipart/form-data'})
resp = urllib2.urlopen(r)
code = resp.getcode()
data = resp.read()

我也尝试过使用MultipartPostHandler：

import MultipartPostHandler,urllib2,cookielib
cookies = cookielib.CookieJar()

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies),MultipartPostHandler.MultipartPostHandler)

params = {
    "name":"bob","description":"riviera","content" : open("poza.jpg","rb")
}

opener.open("http://localhost:8000/api/image/",params)

但相同：500或400错误和服务器(python manage.py runserver)停止,并出现以下错误：

Exception happened during processing of request from ('127.0.0.1',64879)
Traceback (most recent call last):

如果有人有,请给我一个用文件发布数据的例子或告诉我发布python代码有什么问题.我找不到更多的例子了.

服务器看起来不错,我可以在浏览器中发布数据.非常感谢你.
